6.1.6 VISA
VISA is a standardized software interface library providing input and output functions to
communicate with instruments. The I/O channel (LAN or USB) is selected at initializa-
tion time by means of a channel-specific resource string. For more information about
VISA, refer to its user documentation.
6.2 Setting Up Remote Control Connection
USB
The following shows the resource string format used when setting up a remote connec-
tion via the USB interface:
●
USB TMC
USB0::0x0AAD::
0x0197::5601.1414<device_variant>-<device_serial_number>::
INSTR where k03 is used for 3-ch device, k02 for 2-ch device. (e.g.
USB0::0x0AAD::0x0197::5601.1414k03-100689::INSTR)
●
USB VCP
ASRL<COM>::INSTR, where "COM" refers to the COM port number shown on the
controlling PC. (e.g. ASRL15::INSTR)
LAN/WLAN
Refer to
and WLAN parameters.
To set up the connection the IP address of the instrument is required. It is part of the
resource string used by the program to identify and control the instrument. The
resource string has the form:
TCPIP::‹IP_address›::INST
Example: If the instrument has the IP address 192.1.2.3; the valid resource string is:
TCPIP::192.1.2.3::INST
Higi-Speed LAN INstrument Protocol (HiSLIP) is a TCP/IP-based protocol for remote
instrument control of LAN-based test and measurement instruments. It was specified
by the IVI Foundation and is intended to replace the older VXI-11 protocol. To start
remote control session with HiSLIP, the valid resource string is:
TCPIP::192.1.2.3::HISLIP
The end character must be set to line feed (LF).
